The "speed limit 10%" is a common but unofficial guideline suggesting police might ignore minor speeding (around 10% over the limit), but it's a myth for official enforcement, as penalties (fines, points) often start for going just 1-10 km/h over the limit in places like Australia, while UK police often use a "10% + 2 mph" tolerance, meaning it's risky to rely on it, as actual limits (like 10 km/h shared zones or 50 km/h urban limits) and strict local rules always apply.
Speed camera margins of error (or "tolerances") vary by location and camera type, often allowing a few km/h or a small percentage (e.g., 3 km/h for mobile, 2 km/h for fixed in some Australian states) off the recorded speed to account for device inaccuracy, but this isn't guaranteed and can change, so the safest bet is always to drive the posted limit to avoid fines.
Speed camera tolerance refers to the margin of error or buffer added to a vehicle's detected speed before a fine is issued, typically around 10% plus a small fixed number (e.g., 2-3 mph/km/h) for guidance, though this varies by region and police force, with some locations having specific rules (like 2 km/h for fixed cameras in Victoria) or no official tolerance at all (like WA). This buffer accounts for speed camera inaccuracies and vehicle speedometer variations, but it's only guidance, and police can choose stricter enforcement.
Speed limits are enforced in all areas of the country. Tolerance is about 6 km/h in urban areas and 9 km/h on highways depending on regulations of respective state such that driver driving on or below the tolerance speed will not receive a ticket.
You can get a speeding ticket for going any amount over the limit, but most places have a small tolerance (like 10% + 2 mph or a few km/h) before enforcement cameras consistently catch you; however, a police officer can ticket you for even 1 km/h over, especially in school zones or for higher speeds, leading to fines, demerit points, or license suspension.
A Band A speeding fine would be appropriate if you were caught speeding between 31-40 mph in a 30-mph zone. Providing you accept responsibility for speeding, you will be required to pay a minimum £100 fine and receive three points on your licence.
The "best" excuse for a speeding ticket appeal is usually a legally recognized defense, like a medical emergency, an unavoidable situation (e.g., vehicle breakdown), or proving the speed detection equipment was faulty, as these address the circumstances of the offense, not just an excuse. Common, though less reliable, excuses involve "I didn't see the sign" or "keeping up with traffic," but these often fail in court; being respectful and challenging the evidence (like radar calibration) offers a better chance.
No, driving 10 km/h under the speed limit isn't inherently illegal, but it can become an offense if it unreasonably obstructs traffic, meaning you're causing congestion or disrupting the flow, especially if you're in the wrong lane or on a fast road without good reason. There's no set minimum speed, but police can fine you under laws like Australia's Rule 125 for impeding other drivers, making the legality dependent on road conditions and your actions.
You have been caught exceeding the speed limit by a considerable amount and may face a fine of 125-175% of your weekly income, along with six penalty points or a driving ban. Depending on the severity of the offence, it may result in a dangerous driving charge that can result in imprisonment.
In Australia, speeding is driving even 1 km/h over the posted speed limit. Unlike in some countries where limits are treated as guidelines, Australia enforces strict speed limit penalties.
The mobile speed cameras using radar can detect your speed from several hundred metres away. However, for an accurate, prosecutable reading, the operator typically needs to be within a few hundred metres. The key point is they will have your speed locked in well before you get close enough to spot them.
Tolerances allow for minor discrepancies without penalising drivers who are trying to comply with the law. In the UK, the most commonly quoted tolerance is 10% + 2mph over the speed limit. For example, a speed camera on a 30mph stretch of road might not activate until you exceed 35mph.
A speedo must never show less than the actual speed, and must never show more than 110% of actual speed + 6.25mph. So if your true speed is 40mph, your speedo could legally be reading up to 50.25mph but never less than 40mph.
If you're caught driving 100 mph or more, you may be facd criminal speeding charges that could potentially result in a misdemeanor or felony. Criminal speeding typically involves two factors: Driving at extremely high speeds (e.g., 100 mph or more) Driving recklessly or in a way that endangers others.
These incidents highlight that while speed cameras are generally reliable, they are not infallible. This opens up the possibility of challenging fines in certain circumstances. It's important to note that speed cameras in NSW undergo regular testing and calibration to ensure their accuracy.
Speed and red-light camera penalties typically arrive within two weeks, although NSW can take up to 28 days. In Tasmania, fines may appear electronically in as little as four days.
Speeding between 31 and 40 mph in a 30 mph zone constitutes three penalty points on your driving license. In addition to penalty points, a fine amounting to a proportion of your weekly income will also be imposed. More severe speeding offences can attract larger fines.
If you're caught driving over the 20mph limit and aren't offered a speeding awareness course, then you'll be fined and have at least 3 points added to your license. You'll need to disclose the conviction to your insurance company and your premium will undoubtedly rise.

The minimum speeding fine varies significantly by location (state/territory in Australia, for example) and how much you exceed the limit, but generally starts around $100 AUD for exceeding the limit by the smallest margin (e.g., less than 10 km/h), with some areas like Western Australia having no demerit points for this smallest infraction, while NSW might have a $93 fine for similar minor speeding, and South Australia starts at $187 with points.
Exceeding the speed limit by more than 15 mph (24 km/h) with a speed of greater than 55 mph (89 km/h) or travelling faster than 80 mph (129 km/h) results in a minimum 30-day license suspension.
The most believable excuses are short, specific, and tied to legitimate responsibilities or unavoidable situations. Examples include sudden illness, a medical appointment that couldn't be scheduled outside work hours, urgent family needs, or car/transportation issues.

The best defense for a speeding ticket often involves challenging the accuracy of the speed measurement, questioning the clarity and visibility of speed limit signs, disputing the officer's observations, or proving a necessity or mistake of fact.
